help? pls

so i was very good friends with this guy M. and i could go to him with all my problems. then the friendship went really down hill and we had a fight and i blocked him. then a couple weeks ago i really needed someone to talk to and i unblocked him. we face timed that night but the next day right after school i blocked him back because i was scared that things would go down hill again. M is known for being a thot and just a not very good person overall. now i’m starting to feel like shit again and i don’t want to unblock him but i have literally nobody else to talk to about all this that’s going on in my life right now. but like i said i’m scared to unblock him again bc i don’t want things to go wrong. i don’t know what to do but i hate holding all my problems inside with nobody to talk to about any of it. I don’t know what to do. please help. i feel like crying basically all the time and sometime i do but nobody notices ever. i feel a little depressed and i don’t feel okay anymore.

edit:

i do not feel comfortable with telling anybody about feeling depressed
